UNITED STATES FRANK R. THALKEN, OF CONEY ISLAND, BROOKLYN, NEW YORK.

PORTABLE JUMPING TOY.

Application filed. April 13, 1923. Serial No. 631,845.

To all whom it may concern.

Be it known that I, FRANK R. THALKEN, a citizen of the United States, residing at Coney Island, Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improve ments in Portable Jumping Toys, of which the following is a specification.

This invention relates to a toy of the type providing a resiliently supported seat which permits of a child jumplng up and down thereon, the present invention presenting certain features divided from a previous application filed by me on June 7, 1922, under Serial No. 556,572. V

The present invention has for an object the provision of a novel form of multiple jumping toy, a further specific object of the invention relating to the adjustment of the seats.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawings is a part side elevation and part central vertical sectional view of a multiple jumping toy constructed according to my invention.

Fig. 2 is a horizontal sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a side elevational view showing a slightly modified form of the toy.

Fig. 4: is a fragmentary central vertical sectional view at right angles to- Fig. 3.

Fig. 5 is a horizontal section on the line 5-5 of Fig. 3.

Referring now to the invention as embodied in Figs. 1 and 2 I provide a square platform or base on which is centrally located an upright cylindrical housing 11. Extending upward in this housing and spaced equidistant from the centre thereof, and from each other, are four posts 12 which are fixed at opposite ends in the platform 10 and the roof of the housing respectively. Upon each of these posts is slidably mounted a sleeve-like crosshead 14 having projecting rigidly therefrom a seat bar 15, whose outer end forms the seat for the child using the toy, and which may have a back 16 in the form of a manikin as indicated. These bars project through vertical slots such as 17 in the housing.

Suitable anti-friction means are provided in connection with each crosshead 14:, this anti-friction means comprising an upper pair of rollers 18 mounted on the crosshead and adapted to engage in grooves 19 in the inner face of the housing wall, and a single lower roller 20 which engages in a vertical groove 21 in a cylindrical standard 22 fixed in the centre of the housing. Each seat is resiliently supported, this being effected by means of compression springs 23 coiled around the posts 12 below the crossheads 1 1 and on which the latter rest.

I preferably provide means whereby the springs may be raised or lowered so as to vary the helght of the seats as desired. As here shown a cam ring 25 is rota-tably seated on the platform 10 concentric with the housing 11 and inside the latter. This ring is formed with a number of arcuate slots 26 extending from top to bottom therethrough and through which the posts 12 extend. Formed on the top of the ring 25 are a number of cam rises 28 one adjacent each slot 26, and as will be apparent, when the ring 25 is rotated these rises may be brought under the springs and so raise the latter. For rotation of the ring 25 worm teeth 30 are formed thereon and are engaged by a Worm pinion 31 suitably mounted in the low er part of the housing and provided with a squlared trunnion 32 to receive an adjusting too In Figs. 3, 4. and 5 I have shown my improved toy in duplex form and comprising a square housing 35 located midway between opposite ends of an elongated platform 36. Extending upward in the housing 35 are four posts 37 between which is positioned a crosshead 38 having upper and lower sets of rollers 39 thereon engaging suitable guides on said posts. From opposite sides of the crosshead 38 project seats 40 through vertical slots in the housing 35. The resilient seat supporting means here comprises the cables 42 attached at one end to the housing and then passing upward over pulleys 43 journaled in fixed elements in the housing, and then downward to connect to coiled tension springs 4a attached to the orosshead 38.

Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United States is as follows:

1. A toy of the type described comprising a platform, a housing supported thereon and formed with a number of vertical slots spaced around the wall thereof, a series of posts in said housing adjacent said slots, crossheads slidable 011 said posts, seat-bars projecting from said crossheads, compres sion springs coiled around said posts under the said crossheads for supporting said crossheads, and a cam ring on which said springs rest having a number of cam rises thereon adapted to be engaged under said springs to support the latter at selected levels. 2. A toy of the type described comprising a platform, a housing, supported thereon and formed with a number of vertical slots spaced around the Wall thereof, a series of posts in said housing adjacent said slots, crossheads slidable on said posts, seat-bars projecting from said crossheads, and spring elements supporting said crossheads, said spring elements consisting of compression springs coiled around the said posts under the said crossheads and a unitary means for adjusting all of said springs together.

3. A toy of the type described comprising a platform, a housing supported centrally thereon and formed with a number of ver tical slots spaced around the Wall thereof, a series of posts in said housing adjacent said slots, a standard in said housing positioned centrally with respect to the said posts, crossheads slidable on said posts, seat-bars projecting from said crossheads through the said slots, upper and lower anti-friction rollers on said crossheads engaging respectively the wall of the housing and the said standard, and resilient means supporting said crossheads, said resilient means comprising compression springs coiled around the said posts, acam ring on said platform under and supporting said spring and having a series of cam rises thereon, and means for rotatably adjusting said cam ring, for the purpose specified.

In testimony whereof I have aflixed my signature.

FRANK R. THALKEN.
